Существенной технической задачей в совершенствовании станков и электрорубанков является повышение производительности и качества обработки древесины, а также снижение энергопотребляемости на единицу строганной площади и единицу объема срезаемой древесины. Однако известные электрорубанки не в полной мере отвечают указанным условиям. Это связано с тем, что строгание древесины на строгальных или рейсмусовых станках, а также строгание древесины ручными электрорубанками ограничивается шириной строганной поверхности, в зависимости от которой выбирают мощность электродвигателя привода станка или электрорубанка. Если габариты электродвигателя для стационарного станка не играют существенной роли, то для ручных электрорубанков выбор компактного электродвигателя ограничивается шириной обрабатываемой поверхности. В этой связи все ручные электрорубанки вследствие малых габаритов электродвигателей имеют такую мощность, которая соответствует строганию древесины сравнительно небольшой ширины. В случае увеличения ширины строгания увеличивают ширину ножей, повышают мощность электродвигателя, его габариты и массу, что в целом повышает массу электрорубанка, снижает удобство его использования и повышает трудоемкость. Все эти недостатки относятся также и к стационарным деревообрабатавающим станкам, потребляемая мощность каждого из которых расходуется на преодоление сопротивления резанию древесины и преодоление сопротивления перемещения заготовки относительно режущей головки. Существенно то, что при увеличении ширины строгания ручными электрорубанками возрастающее сопротивление резанию и перемещению электрорубанка приводит к невозможности использования электрорубанка в качестве ручного инструмента, поскольку по своей массе такой электрорубанок переходит в разряд перемещаемых министанков. An essential technical task in improving machine tools and electric planers is to increase productivity and quality of wood processing, as well as reduce energy consumption per unit of planed area and unit volume of cut wood. However, the known electric planers do not fully meet the specified conditions. This is due to the fact that wood planing on planing or thicknessing machines, as well as wood planing with manual electric planers, is limited by the width of the planed surface, depending on which the power of the machine drive electric motor or electric planer is selected. If the dimensions of the electric motor for a stationary machine do not play a significant role, then for manual electric planers the choice of a compact electric motor is limited by the width of the surface to be machined. In this regard, all manual electric planers, due to the small size of electric motors, have such a power that corresponds to planing a relatively small width of wood. In the case of increasing the width of the planing, increase the width of the knives, increase the power of the electric motor, its dimensions and weight, which generally increases the mass of the electric planer, reduces the convenience of its use and increases the complexity. All these disadvantages also apply to stationary woodworking machines, the power consumption of each of which is spent on overcoming the resistance to cutting wood and overcoming the resistance to movement of the workpiece relative to the cutting head. It is significant that with an increase in the width of planing with handheld electric planes, increasing resistance to cutting and moving the electric planer makes it impossible to use the electric planer as a hand tool, since by its mass such an electric planer goes into the category of movable mini-machines.
Техническим результатом предложенного технического решения является уменьшение затрачиваемой мощности на обработку древесины.  The technical result of the proposed technical solution is to reduce the power spent on wood processing.
Технический результат получен электрорубанком, характеризующимся тем, что он содержит корпус, установленный в корпусе приводной ротор с закрепленными в нем, по меньшей мере, двумя ножами, имеющими режущие кромки, смещенные относительно друг друга по длине ротора, причем режущие кромки ножей выполнены в виде гребенок, имеющих прямоугольные зубья, между которыми выполнены выемки, и каждая гребенка одного ножа в проекции на фронтальную плоскость расположена в контуре выемки второго ножа.  The technical result is obtained by an electric planer, characterized in that it comprises a housing mounted in the drive rotor housing with at least two knives fixed therein having cutting edges offset relative to each other along the length of the rotor, the cutting edges of the knives being made in the form of combs having rectangular teeth, between which recesses are made, and each comb of one knife in projection onto the frontal plane is located in the contour of the recess of the second knife.
Технический результат получен также ножом электрорубанка, содержащим основание и режущую кромку, причем режущая кромка выполнена в виде гребенки, имеющей прямоугольные зубья, между которыми выполнены выемки.  The technical result was also obtained with an electric plane knife containing a base and a cutting edge, the cutting edge being made in the form of a comb having rectangular teeth between which recesses are made.
На фиг.1 схематично показан электрорубанок; на фиг.2 - вид А на фиг.1 ; на фиг.З - нож электрорубанка.  Figure 1 schematically shows an electric planer; figure 2 is a view of figure 1; in Fig.Z - knife electric.
Электрорубанок содержит условно показанный, в виде опор корпус 1 (фиг.1), установленный в корпусе на валу 2 приводной ротор 3 с закрепленными в нем, по меньшей мере, двумя ножами 4 и 5, симметрично установленными относительно оси ротора и вертикальной плоскости, в которой расположены режущие кромки ножей. Режущая кромка каждого ножа выполнена гребенчатой и образована множеством зубьев, каждый из которых имеет режущую кромку. Под режущей кромкой ножа понимается совокупность режущих кромок каждого зуба ножа. Под режущей кромкой зуба ножа понимается острие зуба ножа, расположенное на коническом основании зуба, причем основание зуба образовано фаской, полученной при выполнении угла заточки зуба. Эти углы заточки зубьев равны. The electric plane contains a conditionally shown, in the form of supports, housing 1 (Fig. 1) mounted in the housing on the shaft 2 of the drive rotor 3 with at least two knives 4 and 5 fixed therein, symmetrically mounted relative to the rotor axis and the vertical plane, in which are the cutting edges of the knives. The cutting edge of each knife is made comb and is formed by many teeth, each of which has a cutting edge. By the cutting edge of the knife is understood the set of cutting edges of each knife tooth. By the cutting edge of a knife tooth is meant the point of a knife tooth located on the conical base of the tooth, the tooth base being formed by a chamfer obtained by performing the angle of sharpening the tooth. These tooth sharpening angles are equal.
Первый нож 4 имеет режущую кромку, образованную режущими кромками зубьев 6, каждый из которых имеет прямоугольную форму, образованную передней стороной 8, и боковыми сторонами 9. Стороны 9 ножа и его внутренние стороны 10 образуют собой прямоугольные выемки 1 1 , расположенные между зубьями 6.  The first knife 4 has a cutting edge formed by the cutting edges of the teeth 6, each of which has a rectangular shape formed by the front side 8 and the sides 9. The sides 9 of the knife and its inner sides 10 form rectangular recesses 1 1 located between the teeth 6.
Второй нож 5 имеет аналогичную форму, при этом зубья 12 второго ножа 5 смещены относительно зубьев 6 первого ножа 4 на величину, равную длине выемки 11 первого ножа 4. В этой связи каждый зуб 6 первого ножа 4 расположен в контуре выемки 13 второго ножа 5 в проекции на вертикальную плоскость в положении ротора, повернутого вокруг своей оси на 180°. Режущие кромки ножей расположены в вертикальной плоскости 14 (фиг.2) и при этом каждая режущая кромка равноудалена от цента 15 ротора 3.  The second knife 5 has a similar shape, while the teeth 12 of the second knife 5 are offset relative to the teeth 6 of the first knife 4 by an amount equal to the length of the recess 11 of the first knife 4. In this regard, each tooth 6 of the first knife 4 is located in the contour of the recess 13 of the second knife 5 in projections on a vertical plane in the position of the rotor, rotated around its axis by 180 °. The cutting edges of the knives are located in the vertical plane 14 (figure 2) and each cutting edge is equidistant from the center 15 of the rotor 3.
Каждый нож электрорубанка выполнен в виде пластины 16 (фиг.З), которая имеет основание 17 и режущую кромку 18, образованную множеством зубьев 6, причем режущая кромка 18 зуба 6 в совокупности с режущими кромками других зубьев 6 образует режущую гребенку во фронтальной плоскости ножа. Зубья ножа выполнены прямоугольными в указанной плоскости и между ними выполнены прямоугольные выемки 11. Каждый зуб 6 ножа имеет фаску 19, соответствующую углу заточки режущей кромки 18 ножа.  Each knife of the electric planer is made in the form of a plate 16 (FIG. 3), which has a base 17 and a cutting edge 18 formed by a plurality of teeth 6, moreover, the cutting edge 18 of the tooth 6, together with the cutting edges of the other teeth 6, forms a cutting comb in the frontal plane of the knife. The teeth of the knife are made rectangular in the indicated plane and rectangular recesses 11 are made between them. Each tooth 6 of the knife has a bevel 19 corresponding to the angle of sharpening of the cutting edge 18 of the knife.
Работают электрорубанок и нож следующим образом.  Work electric and knife as follows.
При вращении ротора 3 сначала нож 5 (фиг.2) прорезает зубьями 12 канавки на поверхности строгаемой древесины и при этом между канавками на поверхности древесины образуются гребни. При резании массива древесины связи между ее волокнами разрушаются и затрачивается первая доля мощности на прорезание канавок. После поворота ротора на угол 180° древесину режут зубья 6 ножа 4 и срезают указанные гребни древесины. При этом затрачивается вторая доля мощности на обработку древесины, которая меньше первой доли мощности. Это связано с тем, что при затрате второй доли мощности происходит частичное скалывание гребней между канавками древесины зубьями 6 ножа 4, что существенно снижает потребляемую мощность электрорубанком. When the rotor 3 is rotated, first the knife 5 (Fig. 2) cuts with its teeth 12 grooves on the surface of the planed wood and between Grooves form ridges on the surface of the wood. When cutting an array of wood, the bonds between its fibers are destroyed and the first fraction of the power is used for cutting grooves. After the rotor rotates through an angle of 180 °, the teeth 6 of the knife 4 are cut into the wood and the indicated ridges of the wood are cut. In this case, a second share of the power is spent on wood processing, which is less than the first share of the power. This is due to the fact that when the second share of power is consumed, the ridges between the wood grooves partially chisel with the teeth 6 of the knife 4, which significantly reduces the power consumption of the electric planer.
При вращении ротора и его перемещении (показано стрелками на фиг.2) зубья попеременно указанным образом обрабатывают поверхность древесины и при этом они зачищают поверхность строгаемой древесины так, что образуется сплошная ровная обработанная поверхность.  During the rotation of the rotor and its movement (shown by arrows in FIG. 2), the teeth alternately process the surface of the wood in the indicated manner and at the same time they clean the surface of the planed wood so that a continuous, uniform processed surface is formed.
Таким образом, в процессе строгания древесины сначала происходит разрушение связей между ее волокнами от действия ножа 5, а затем зачистка образовавшихся на древесине гребней ножом 4, что в итоге существенно снижает сопротивление древесины во время снятия с нее стружки и уменьшает потребляемую мощность электрорубанка. За счет этого длина ротора, ножей и ширина захвата ножами строгаемой поверхности существенно увеличены, производительность повышена, а усилие перемещения электрорубанка уменьшено. Установка описанных выше ножей на стандартном электрорубанке обеспечивает возможность уменьшения мощности электродвигателя на 20-30% от номинальной мощности электродвигателя стандартного электрорубанка.  Thus, in the process of wood planing, the bonds between its fibers are first broken by the action of the knife 5, and then the ridges formed on the wood by the knife 4 are cleaned, which ultimately significantly reduces the resistance of the wood during removal of chips and reduces the power consumption of the electric planer. Due to this, the length of the rotor, knives and the width of the knives of the planed surface are significantly increased, productivity is increased, and the effort of moving the electric plane is reduced. The installation of the knives described above on a standard electric plane provides the ability to reduce the power of the electric motor by 20-30% of the rated power of the electric motor of a standard electric plane.
